auctex: Unbinding
A.5.4 Which native mode key bindings are missing
------------------------------------------------
The following commands from the native commands might still be useful
when working with AUCTeX, however, they are not accessible with a key
binding any longer.
'@node' insertion
The node insertion command, mapped to 'C-c C-c n' in the native
mode, is not mapped to any key in AUCTeX. You can still access it
through the Texinfo menu, though. Another alternative is to use
the 'C-c C-m' binding for macro insertion in AUCTeX.
Show the section structure
The command 'texinfo-show-structure' ('C-c C-s') from the native
mode does not have a key binding in AUCTeX. The binding is used by
AUCTeX for sectioning.
